Title: John M Criscione: Innovator in Carbon and Graphite Technologies

Introduction

John M Criscione is a notable inventor based in Parma, OH (US), recognized for his contributions to the field of carbon and graphite technologies. With a total of 3 patents, Criscione has made significant advancements that enhance the production and properties of carbon-based materials.

Latest Patents

Criscione's latest patents include a process for producing high-density carbon and graphite articles. This innovative method involves blending carbonaceous powders with a high coking value pitch, such as mesophase pitch, which is then formed into shaped bodies. These bodies are simultaneously compressed and baked in an envelope of finely divided, non-reactive particles, followed by graphitizing if required. This process results in high-strength, high-density carbon or graphite articles.

Another significant patent is for making pitch-free graphitic articles. This process creates high-density composites consisting of graphite and metal borides by pressing blended powders of pitch-free coke and boride powder. The pressing can be conducted through hot pressing at temperatures around 2200°C and pressures of about 1500 psi, or cold pressing at room temperature followed by high-temperature sintering. The resulting mechanical strength of these composites is comparable to, and often exceeds, that of conventional graphites, while also offering superior oxidation resistance at elevated temperatures.
